I am going to put a 440 and auto tranny in a 74 duster, I have rebuilt the suspension front and rear, upgraded to an 8-3/4 with 742 case with 3:23 gears and limited slip. My question is the wiring, the existing wiring harness is pretty much useless. It was a 318 auto with coloumn shift, I could repair it If I really wanted to but, what is another way to do it? I repainted the engine compartment and am getting ready to do the rest of the car.
